I was wondering if a male of one type of strain can pollinate a totally different strain? Of course there a different strains availabe that are a combination of different strains, but can one of us develop a new strain of different plants that does not exist and produce seeds and replant these seeds for a totally different strain that what is currently available?

For example, if I just plant to seeds, 1 white widow and 1 ICE and 1 turns out to be female and the other male will the male pollinate the female of the different strain? If not, then I guess there is no worry in letting the male grow. Otherwise, it is important for newbies like me to learn as quick as possible in recognizing a male and female. Newbie does not want a male to pollinate and does not want to yank a female by accident.
